FREDERICK W. VAN FLEET, OF MOUNT BLANCHARD, OHIO.

JOINT FOR SCREENS AND OTHER FRAMES.

To all whom fit 'may concern:

Be it known that I, FREDERICK W. VAN FLEET, a citizen of the UnitedStates, and a resident of Mount Blanchard, in the county of Hancock andState of Ohio, have invented certain new and useful Improvements inJoints for Screens and Other Frames, of which the following is aspecification.

My invention relates to improvements in joints for screen and otherframes and has for its object to provide a joint which shall be simple,cheap and eflicient and one which renders a frame rigid and permits ofmaking frames of various sizes.

My invention consists in certain novel features of construction,arrangement and combination of parts as will be hereinafter fullydescribed and pointed out in the claims, reference being had to theaccompanying drawings, in whichw j lligure l is a perspective view ofone corner of a screen frame showing my improvements applied. F ig. 2 isa sectional elevation of same corner. Fig. 3 is a vertical section ofsame. Fig. 4 is a horizontal section taken on line 4 4 of Fig, 3. Fig. 5is a vertical section taken on line 5 5 of Fig. 2.

In carrying out my invention I make the horizontal rail or stile D witha small shoulder, cut back as far as the first groove so that themolding A which holds the wire screen B will fit without trimming. Therail or stile A is slittedas at A2 from the inner edge and in this slitis placed the metal tenon or plate C which has a projecting head portionC, the

lower face of which is formed with teeth c; the tenon also has a smallhole c through which a pin c2 is driven from the inner face of thevertical rail when the tenon is properly placed.

The horizontal or stile rail D is slitted as at D to receive the head Cof the tenon or anchor plate C, and a small hole D2 is bored through therail D from the slit to a recess or socket D3 formed in the upper faceof the rail D g a straining bolt E with a hook E at its lower end andthreaded -at its upper end is passed through hole D2 into the slit D andthe hook E turned to enter a hole C3 in the head C of the tenon oranchor plate C; a nut E2 and a washer E3 is to be screwed on thethreaded end of the bolt E, the nut and washer resting in the socket D3which is of sullicient size to permit turning of the nut by a suitabletool.

The parts of'the frame are to be sold and Speccation of Letters Patent.

shipped in a knock-down condition and ut together in the followingmannerz-lhe rails or stiles being cut to the desired size, the tenon oranchor plate C is slipped into the slit A2 and tapped lightly on theupper end to cause the teeth c to bite into the rail A and hold itfirmly in position. The slitted end of rail D is now brought toward therail A the tenon C entering the slit D the bolt E having been previouslypassed through the hole D2 and the nut screwed on its upper end; themeeting ends of the rails are now in the desired position, the hook E isturned so as to engage the hole C3; a small pin C2 is now driven throughthe front face of the rail and through the hole c in the tenon; to makethe joint tight and rigid it is now only necessary to turn the nut onthe bolt E in the socket D3 which draws the ends of the two railsclosely together. The screen netting is now secured to -the frame bymeans of the molding strips A which are grooved as atf on their rearface, said grooves corresponding to grooves d in the face of the rails,the grooves serving to crimp the wire netting and hold it againstslipping.

The screens are to slide on outside of and against the blind stops andflush with outer face of window casing, and the screens can be used foreither upper or lower half of window; a small strip of wood of the samethickness as the blind stop, is fastened at either end of the stop andlills space between window sash and screen frame, whether screen be upor down; the strip is fastened by small pieces of tin or metal tacked tothe ends after it is cut to proper length, and projecting on upper andlower sides, to be tacked to the blind stops.

By the use of my improvements, the frames are rendered adjustable to anysize, both as to length and width. Such a frame has all the advantagesof a mortise and tenon frame, and has an advantage over such a framewhich is naturally weakened by the mortise and tenon, in that I use onlyslits and a metal tenon which does not rot, and by the use of the boltand nut the frame may be tightened at any time should it become loose byshrinkage or drying out.

I claim:

1. A joint for frames comprising two angularly abutting rails or stileshaving slits in their adjacent ends, a metallic anchor plate or tenonremovably held in the slit of one rail and having a laterally projectinghead portion having teeth on its lower edge, and a straining boltmounted in the other' rail and extending into the slit thereof andengaging the aforesaid metallic anchor plate or tenon. 2. A joint forframes, comprising tWo rails abutting at an angle to each other andhaving slits or sockets at their abutting ends, a flat metallic anchorplate held Within the slit in one rail, and a straining bolt mounted inthe other rail and extending into the slit thereof and engaging the saidanchor plate.

3. A joint for frames comprising tWo angularly abutting rails or stiles,said rails or stiles having slits in' their adjacent ends, a removablelat metallic anchor plate mounted in the slit of one rail or stile,vandhaving an aperture near the end, a straining bolt bent at one end toform a hook, mounted in the other rail or stile, said hook endprojecting into the slit of its rail and engaging the aperture in themetallic anchor plate or tenon, 1nld a nut engaging the threaded end ofthe o t. 4. A joint for Vframes comprising tWo angularly abutting railsor Stiles, having slits at their adjacent ends, a metallic anchor plateor tenon removably held in the slit of one rail and having a laterallyprojecting head portion provided with teeth on its lower edge, andhaving an aperture therethrough, a straining bolt mounted in the otherrail and bent at one end to form a hook, said hook end projecting intothe slit of its rail and engaging the aperture in the head of themetallic anchor late or tenon, a nut engaging the threaded) end of saidstraining ibolt, said nut adapted to be seated in a socket in the edgeof the rail carrying said bolt.

5. A joint for frames comprising two angularly abutting rails or stileshaving slits in their adjacent ends, a metallic anchor plate or tenonremovably held in the slit of one rail and having a laterally projectinghead portion, and a straining bolt mounted in the other rail andextending into the slit thereof and engaging the aforesaid anchoi1 plateor tenon.
